To all when?, t may concern:

Bo it known that l, ALFRED Cnfrcnrotn, of

teneva, in the county of Ontario, in the State of New York, have invented new and useful Improvements in Latheaof which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to provide a lathe which shall be simple and compact in construction and convenient in its operation, and adapted for turning large heavy Work such as the main driving-pulleys of engines and analogous Wheels as Well as shaftings or other long and slender Work.

To that. end the invention consists of a headstock and a tool-rest support extending along the side of said head-stock and adjustable laterally toward and from the same to accommodate Wheels or analogous Work of various diameters on the chuck-plate or face-plate of the lathe.

The invention also consists in the combina` tion, with the head-stock, of shears detachably connected thereto.

The invention furthermore consists in cer tain novelties of the details of the lathe all as hereinafter more fully described and specifically set forth in the claims.

ln the annexed drawings Figures l and 2 are respectively side and end. elevations of the head-stock arranged for turning large ivorluFig. 3 is a side elevation of the lathe in position for turning shafting or other long slender Work, Fig. e is a plan view of the saine, and Fig. 5 is a detail vieiv of one of the legs which support one end of the shears.

Similar letters of reference indicate corre spending parts.

A- represents the head-stock, and -B the shears which I detachably secure to said head-stool; for the purpose of allowing large work to be attached to the chncloplate or faceplate -tl For operating on such Work l provide at the side of the head-stock Afa snitable support "D for the tool-rest Ma, which support is adjustable laterally toward and from the side of the head-stock in any suitable manner. Said support -D-- consists mainly of a longitudinal beain mounted on cross beams MIL-F- secured to the hea-dstock and extending laterally from the sides thereof. Said cross-beams may be either of Wood or of metal and pass through sleeves ZJ- so as to allow the said cross beams to be shifted longitudinally and extend to a greater or less distance from the side of the head-stock. A set screW-cpassing through the side of the sleeve as indicated by dottedlines in Fig. 3 of the drawings engages the beam and holds the saine in its adjusted position. The longitudinal beam v-D-n is bolted to the tops of the aforesaid cross-beams. l prefer however to forni the cross-beams of metal and With T- shaped longitudinal grooves -d-d in their tops and bottoms, and mount them on brackets -b-bformed with horizontal seats -bfor the cross-beams F and perforated for the reception of bolts newhich have their heads in the T-shaped bottom grooves --dand are provided with nuts -n-d on the ends projecting beneath the top-plates or seats of the brackets. By loosening said nuts the cross-beams can be shifted longitudinally as before described and by tightening the nuts said beams are retained in their adjusted positions. The longitudinal beam D-A is secured to the tops of the cross-beams -F-F in the saine inanner by bolts --epassing through the beam -D' and having their heads in the topgrooves -CZ- and provided with nuts on their upper ends. This latter attachment alloivs the longitudinal bearn to be shifted to a greater or less distance from the side of the head-stool; --A- Without disturbing the cross-beams, MIL-F. The range of said adjustment of the longitudinal beam is however augmented by the adjustable attachment of the cross-beams to the brackets -h The end of the shears 1B- adjacent to the headstool; l". support on the cross-beam -F-- in such a manner as to allow said shears to be shifted laterally to one side and thus permit large ivorl; to be attached to the chuck-plate 0. l preferably secure the shears to the cross-beam by means of a plate -P- firmly attached to and extending from the end of the shears and across the top of the beam -F- and provided With bolt holes for the reception of bolts *f*- Which have their heads in the T-shaped top-groove -dof the beam -F- and are provided With nuts on their ends projecting above the plate "P,

IOO

By loosening the nuts the shears can be shifted laterally as before stated and when desired theycan be readily brought back to their normal position directly under the axis of the lathe and clamped in said position and thus adapt the lathe for turning shafts or other analogous work. justment of the shears I either rigidly attach to or form integral with the head-stock A- a lug or suitable stop -h-, and provide the plate -P with a similar lug -z`- in such a position as to cause the two lugs to abut against each other when the shears are brought into their normal position under the axis of the lathe. To allow the shears to be easily shifted as aforesaid I provide the legs -Z-Z--- of the shears with casters the frames of which are pivoted eccentrically to the legs and are provided With suitable handles -Z- by which to turn the caster-frames on their pivots. By means of said handles the casters can be depressed so as to raise the legs from the fioor and-thus allow the shears to be readily shifted as aforesaid, and when the shears 2. The combination, with the head-stock, of

cross-beams secured longitudinally adjustable to said head-stock, and a longitudinal beam mounted on said cross-beam adjustable laterallytoward and from the side of the headstock and supporting the tool-rest as set forth.

3. The combination, with the head-stock -A-, of the brackets -b-brigidly secured to said head-stock and formed with the seats -Z)-b-, the cross-beams -F-F- mounted on said brackets and provided with To facilitate said latter adthe T-shaped longitudinal grooves cZ-cZ in their tops and bottoms, the longitudinal beam --D- mounted on the cross-beams, and bolts -e-ehaving their heads in the aforesaid grooves and fastening the beams in their respective positions as set forth.

4. The combination with the head-stock -A- of the shears -B- supported removably from and to its normal position under the axis of the lathe, as set forth.

5. The combination, with the head stock, of a cross-beam secured to said head-stock and the shears mounted -on said cross-beam and movable laterally thereon as set forth.

6. The combination, with the head-stock -A- of the cross-beams'-F-F, shears WBu mounted on one of said cross-beams adjustably to and from its normal position under the axis of the lathe, and the longitudinal beam `D- extending along the side of the head-stock and mounted on the two-crossbeams, substantially as and for the Vpurpose set forth.

7. The combination, with the head-stock -A-,of they cross-beam -F, the shears -B- mounted on said cross-beam adj ustably to and from its normal position under the axis of the lathe, and stops -tand -iattached respectively to the head-stock Aand shears, substantially as and for the purpose set forth.

8. rIhe combination, with the head-stock -A- and shears -B-, ofthe cross-beam -F- provided with theI T- shaped groove -cZ-- in its top, the plate --P- attached to the shears and riding on the aforesaid beam, and bolts -epassing through said plate and having their heads in the groove --CZ and provided with nuts on their upper ends, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name this lith day of April, 1892.
